They are limiting it by software - not hardware. I am nearly certain about this - I had a similair conversation with my Barracuda rep a few years ago about the spam and virus firewall. He said that even if I upgraded the RAM the box would not change its capabilities.

You might check with Barracda directly to see if they have an upgrade option. At one time (long ago) they did. Also I think they have the Web Filter now as a virtual appliance. Maybe they would be willing to trade you up for a moderate price... assuming you have a VM host to put it on.
